I just joined the ranks of the GAP-nation! I couldn't ignore the lure of the GAP round any longer. I already have all the SF models Glock offers in both .45 ACP and 10mm, and they are all great guns, but I wanted an even shorter frame. Looking at a GAP cartridge close up, I can see the genious behind the design: Shorter case, stronger brass, yet nearly identical ballistics as the much vaunted standard pressure .45 ACP. I really hope this round gains popularity!
